fiPEGIEICATION forming part of Letters Patent No. 664,835, dated January 1, 1901.

Application filed June 23,1899. Serial No. 721,686. (No model.)

To (tZZ whont it ntay concern:

Be it known thatLEnWARD L. CZARNIECKI, a citizen of the United States, and a resident of Aspinwall, county of Allegheny, and State of Pennsylvania, have invented a new Improvement in Boxes, of which the following is a specification.

My invention relates to boxes, and has special reference to folding boxes for use in carrying lunches, dtc.

One object of my invention is to provide a folding box which will present a smooth inside surface when folded into a box form, as well as one which will prevent crumbs, the, from getting in between the folds of the box.

A further object of my invention is to provide such a form of folding box which can be easily and rapidly folded or closed up into a small package, as well as one which can be folded or closed up by a continuous fold.

My invention consists, generally stated, in the novel arrangement, combination, and construction of parts, as hereinafter more specifically set forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use the box, I will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a plan view of the blank from which the box is to be formed. Fig. 2 is a plan View of the blank, showing the ends and side portions of the box folded in and secured to the blank and the same ready for use. Fig. 3 is a like view showing the ends and side portions of the box raised and ready for securing the top or cover and side flap thereto. Fig. 4 is a front view of the box raised up in the position shown in Fig. 3. Fig. 5 is a perspective view of the box ready for use. Fig. 6 is a longitudinal section of the same. Fig. 7 is a perspective view of the box rolled or folded up with the end or side flap secured to the exterior of the same, and Fig. 8 is a like view showing the end or side flap secured within the folds of the box.

Like characters herein indicate like parts in each of the figures of the drawings.

As is shown by the blank A in Fig. 1, my improved folding box 1 is preferably formed from pieces of card or paste board, and these pasteboards are cut to shape to form the front panel 2, bottom panel 3, rear panel 4, top panel 5, end flap 6, and end panels 7. These parts are adapted to be covered over on both sides with cloth or other suitable material, and this cloth is pasted or secured to the parts and forms a bending joint 8 between the panels 4 and 5 and a bending joint 9 between the panels 5 and flap 6. The cloth also forms the bending joints 10 and 11 at the intersections of the front panel 2 and rear panel 4 with the bottom panel 3, as Well as the bending joints 12 at the intersections of the end panels 7 with the bottom panels 3. The cloth extends beyond the sides of the end panels 7, as shown in Fig. 1, to form the side panels 13 of the inner side walls of the box 1 when folded up into position, and these side panels 13 are divided on an oblique line 14 to form the angular portions 15 and 15. The end panels 7 and side panels 13 are adapted to be folded over onto the front panel 2, bottom panel 3, and rear panel 4, as shown in Fig. 2, and the angular portions'15 on the side panels 13 are pasted or secured to the front panel 2 and rear panel 4 to form the space 16 between the end panels 7 and side panels 13. The angular portions 15 are further secured to the panels 2 and 4 by rivets or eyelets 17, extending through the panels 2 and 4 and angular portions 15, and a strap 18 is secured to one of the end panels 7 for engaging with a buckle 19, secured on the opposite end panel 7, When the box 1 is folded or raised into the position shown in Fig. 5. Spring buttons or heads 20 and 21 are secured in the front panel 2 and rear panel 4, respectively, and a button 22, having an opening or seat 23 therein, is secured within the end flap 6.

The manner of constructing and using my improved box is as follows: After the pieces of card or paste board to form the panels 2 3 4 5, flap 6, and panels 7 have been cut to shape and the cloth pasted or secured over the same to form the side panels 13, as shownin Fig. 1, the spring-heads 2O 21 and button 22 are secured in the panels 2 and 4 and end flap 6, and the strap 18 and buckle 19 secured to the end panels 7. After this is accomplished the end panels 7 and side panels 13 are folded over the panels 2, 3, and 4, as shown in Fig.

2, and the angular portions 15 on the side panels 13 secured to the front panel 2 and rear panel 4 by pasting and by the rivets or eyelets 17. The parts are now in position, and when it is desired to use the same as a box all that is necessary is for the operator to grasp each end panel 7 and pull the same outward, so that the end panels 7 and angular portions 15 assume a Vertical position,which will cause the front panel 2 and rear panel 4 to assume upright positions and be brought against the angular portions 15 by reason of the angular portions 15 being secured to said panels 2 and 4. The box 1 will then have assumed the position shown in Figs. 3 and 4 and can be filled while the operator with one hand is holding the panels 2 and 4 against the end panel 7 and angular portions 15, and after the box isfilled the operator with the other hand can bring over the top panel 5 and secure the end flap 6 to the front panel 2 by means of the seat 23 in the button 22 on the flap 6 engaging with the spring button or head 20 on the panel 2. The strap 18 on the end panel 7 can then be inserted in the buckle 19 on the opposite end panel 7 and secured therein, and the box is ready for transporting or carrying, which can be done by grasping or holding the strap 18. When it is desired to empty the contents of the box, all that is required is to unbuckle the strap 18 from the buckle 19, grasp the end flap 6 and pull the same to release the spring-head 20 from the button 22, and throw back the top panel 5 and end flap 6, when the contents can be removed from the box and the parts returned to the position shown in Fig. 2. This being done and it is desired to fold up the box into a small package for convenience in carrying the same in the pocket, all that is necessary is to place the buckle 19 on the end panel 7-the opposite end paneland with the strap 18 folded down, as indicated in Fig. 2, the operator can turn or fold over the front panel 2 onto the strap 18 and end panels 7. Thence the same is turned over onto the angular portions 15 15 and thence turned over again,so that the bottom panel 3 comes against the top panel 5, when the end flap 6 can be brought over against the rear panel 4 and the button 22 thereon secured to spring-head 21 by its seat 23, as shown in Fig. 7, although the end flap 6 can be inserted between the bottom panel 3 and the top panel 5, as shown in Fig. 8, although the former manner of folding it up is preferable.

If desired, the blank A (shown in Fig. 1) can be cut or slit at the dotted line 24, so as to separate the side panels 13 from the front panel 2 and rear panel 4 and leaving the side panels 13 formed as part of the end panels 7, so that the angular portions 15 thereon can be pasted or secured to the front panel 2 and rear panel4under the angular portions 15, as shown by dotted lines in Fig. 6.

It will thus be seen that my improved box is cheap and simple in its construction and operation and can be rapidly and easily folded up into a small package for carrying or transformed into a box form when desired. It can be folded up by a straight or continuous fold, and when so folded makes an exceedingly small and neat package. By its use crumbs, &c. will be prevented from getting within the side panels of the box when raised or folded into position, and when empty the box will stand alone in its raised position. A waterproof coating or cloth can be used upon the.

1. As an improved article of manufacture,

a folding box made in one piece, and consisting of the rectangular bottom 3, the ends 7, 7, the'sides 2, 4, the cover 5, the securing-flap 6, and the four corner-pieces 13, each of the corner-pieces being divided by .a diagonal crease 14 into two plies 15, 15, the plies 15 being permanently secured to the sides 2 and 4; the sides, 2, 4, bottom 3, and top 5 being of the same dimensions, and the flap 6 of the same or less width than any of these, so that the parts are susceptible when fiat of acoutinuous straightaway rolled fold.

2. As an improved article of manufacture, a folding box made in one piece, and consisting of the rectangular bottom 3, ends 7, 7,

sides, 2, 4, cover 5, securing-flap 6,#and four corner-pieces 13, each of the corner-pieces being divided by a diagonal crease 14 into two plies 15, 15, the plies 15 being permanently secured to the sides 2 and 4; the sides 2, 4, bottom 3, and top 5, being of the same dimensions and the flap 6 of the same or less width than these parts, so that all the parts are susceptible when flat of a continuous straightaway rolled fold; the sides 2 and 4 being provided with exterior button-heads 20 and 21 adapted respectively to engage with an interior seat 22 on the flap 6 whenthe box is in an open position and folded closed position.

In testimony whereof I have hereunto set my hand, at Pittsburg, in the county of Allegheny and State of Pennsylvania, this 20th day of June, A. D. 1899.
